2023 Map of Barker Canyon

About this map

Banks Lake dominates the southern reaches of this landscape, where the waters of the Coulee meet the high desert terrain of the Columbia Plateau. The map centers on the dramatic erosional features of the region, including the winding Barker Canyon and the prominent heights of Steamboat Butte and Barker Butte. The terrain is marked by the distinct geology of the Channeled Scablands, where Foster Coulee and Cache Butte stand as enduring markers of glacial flood history. This modern survey follows the boundary between Douglas and Grant Counties, showing the sparse network of rural routes such as RD 26 Ne and Barker Canyon Rd that provide access to the secluded Barker Canyon Lake.
